Tim Kroessig, Harold L. Lyon Arboretum The Hawaiian flora represents ~45% of all plants listed by the U.S. Fish and Wildlife Service as threatened or endangered. The Lyon Arboretum’s Seed Conservation Laboratory (Lyon S.C.L.) conserves many of these imperiled plants through conventional seed banking. However, the seeds of many rare Hawaiian plants have never been […]

Anne Frances, NatureServe Conservation Status Assessments evaluate species’ risk of extinction and are therefore often the first step in prioritizing conservation actions. Red List Assessments (redlist.org) are widely used in globally while the NatureServe Network’s Ranks are more commonly used in the United States and Canada. Although methodologies between the platforms differ, much of information […]

Prioritizing species, populations, and regions for ex situ collecting: Threatened native U.S. oaks as a case study

Screenshot from Prioritizing species, populations, and regions for ex situ collecting: Threatened native U.S. oaks as a case study video

Oaks are keystone species across the majority of forest and shrubland habitats in the United States, but many are threatened with extinction in the wild. Ongoing conservation efforts exist for some native U.S. oak species, but growing threats and limited resources necessitate prioritization and coordination. To that end, The Morton Arboretum, BGCI-US, and the U.S. […]

Matthew Albrecht, Missouri Botanical Garden Monitoring is a central component of reintroduction programs, but often receives less attention from practitioners than the preparation or implementation phases of a project. A well-designed monitoring program can detect changes in the environment over time, identify new threats that emerge at the reintroduction site, determine drivers of growth rates […]
